Powering The Camera
The dome requires either a 12V DC regulated power supply or
a 24V AC power supply it draws a maximum current of around
150mA @12V DC.
Connections are not polarity sensitive therefore the power can
be connected either way round, the power terminals are easy
to identify as they are
marked in red
.
There are four easy ways to cable the camera:
1
RG59+2
No Balun required - easy and simple installation.
2
RG59+4
No Balun required - extra cores allow a DVR with RS485
to control the camera’s OSD.
3
CAT5+2
Requires a balun at the remote end - heavy duty power
cores can power multiple cameras. OSD control by
DVR possible.
4
CAT5
Requires a balun at the remote end - uses the CAT5 cores
for power (Powers single cameras only). OSD control by
DVR possible.
24V AC is a good choice on long cable runs to power the
camera as you get less voltage drop in the power cores,
however if using 24V AC use only CAT5+2 or RG59+2 to avoid
the AC signal interfering with the video signal.
